Study Notes
Equipment and Supplies Used in Venipuncture
- General blood collection equipment includes a blood-drawing station, phlebotomy chair, equipment carrier, gloves, antiseptics, disinfectants, and hand sanitizer.
- Venipuncture equipment includes vein-locating devices, tourniquet, needles, needle gauge, and evacuated tube system (ETS).
Antiseptics and Disinfectants
- EPA-registered sodium hypochlorite is used as a disinfectant with a 1:100 dilution for general cleaning and 1:10 dilution for spills, requiring a 10-minute contact time.
- Antiseptics used include 70% ethyl alcohol, 70% isopropyl alcohol, benzalkonium chloride, chlorhexidine gluconate, hydrogen peroxide, povidine-iodine, and tincture iodine.
Phlebotomy Needles
- Types of phlebotomy needles include multi-sample needles, hypodermic needles, and winged infusion needles.
Evacuated Tube System (ETS) and Syringe System Components
- Syringe system components include a syringe needle with a resheathing feature and a syringe with a graduated barrel and plunger.
- ETS components include multi-sample needles, tube holders, and evacuated tubes, which prevent exposure of the specimen to contaminants.
Categories of Additives Used in Blood Collection
- Categories of additives include anticoagulants, special-use anticoagulants, antiglycolytic agents, clot activators, thrixotropic gel separators, and trace element-free tubes.
Color Coding in Identifying Additives in Blood Collection Tubes
- Color coding is used to identify additives in blood collection tubes, with different colors corresponding to specific additives (e.g., red for no additive, orange for coagulant, etc.).
Order of Draw
- The order of draw refers to the specific sequence of collecting blood samples to prevent cross-contamination, with different tube stopper colors corresponding to different types of tubes (e.g., yellow for blood culture, light blue for coagulation tube, etc.).
